TERRAFORMING TERRA
We discuss and comment on the role agriculture will play in the containment of the CO2 problem and address protocols for terraforming the planet Earth.
A model farm template is imagined as the central methodology. A broad range of timely science news and other topics of interest are commented on.

CO2 Warmth Link Reversed and Immediate

This is extraordinarily important
to our understanding of climate science and begins the disentangling of the
erroneous theory of Anthropogenic Global warming.The argument in favor of CO2 as a climate
driver was always seriously suspect and this blog from the very beginning in
2007 chose to keep the rising CO2 phenomena separate from climate trends and
theory.

Now we have a potent argument
that CO2 levels are determined by the heat content of the atmosphere but not
the other way around.

In fact ice history said as much
and certainly was the chief reason few geologists supported the AGW theory.

This work makes the linkage much
more immediate.The much discussed decadal
lag time disappears and never existed.In fact, a higher CO2 levels implies a warmer environment.

Carbon dioxide is emitted by human activities as well as a host of
natural processes. The satellite record, in concert with instrumental
observations, is now long enough to have collected a population of climate
perturbations, wherein the Earth-atmosphere system was disturbed from
equilibrium. Introduced naturally, those perturbations reveal that net global
emission of CO2 (combined from all sources, human and natural) is controlled by
properties of the general circulation – properties internal to the climate
system that regulate emission from natural sources. The strong dependence on
internal properties indicates that emission of CO2 from natural sources, which
accounts for 96 per cent of its overall emission, plays a major role in
observed changes of CO2. Independent of human emission, this contribution
to atmospheric carbon dioxide is only marginally predictable and not
controllable.

Professor Murry Salby holds the Climate Chair at MacquarieUniversity
and has had a lengthy career as a world-recognised researcher and
academic in the field of Atmospheric Physics. He has held positions at leading
research institutions, including the USNationalCenter
for Atmospheric Research, PrincetonUniversity, and the University
of Colorado, with invited
professorships at universities in Europe and Asia.
At MacquarieUniversity,
Professor Salby uses satellite data and supercomputing to explore issues
surrounding changes of global climate and climate variability over Australia.
Professor Salby is the author of Fundamentals of Atmospheric Physics, and
Physics of the Atmosphere and Climate due out in 2011. Professor Salby’s latest
research makes a timely and highly-relevant contribution to the current
discourse on climate.

The podcast for his talk is here.
Unfortunately there is no video so you can’t see his graphs. But
the talk is very lucid, you can certainly get the point. The entire
podcast is an hour, with his formal presentation about a half hour, and
questions for the remaining half hour.

This talk was given in June at the IUGG meeting
in MelbourneAustralia, and apparently created
quite a stir. A journal paper is in press, expected to be
published in about 6 months. Some of the results will be in his
forthcoming book Physics
of the Atmosphere and Climate that will be available Sept 30.

Salby’s argument is that the usual evidence given for the rise in CO2
being man-made is mistaken. It’s usually taken to be the fact that as carbon
dioxide concentrations in the atmosphere increase, the 1 per cent of CO2 that’s
the heavier carbon isotope ratio c13 declines in proportion. Plants, which
produced our coal and oil, prefer the lighter c12 isotope. Hence, it must be our
gasses that caused this relative decline.

But that conclusion holds true only if there are no other sources of
c12 increases which are not human caused. Salby says there are – the huge
increases in carbon dioxide concentrations caused by such things as spells of
warming and El Ninos, which cause concentration levels to increase
independently of human emissions. He suggests that its warmth which tends
to produce more CO2, rather than vice versa – which, incidentally is the story
of the past recoveries from ice ages.

The Earth’s carbon cycle is not a topic on which I have any expertise.
A good overview article is provided by NASA’s earthobservatory.

Climate models have begun to include an interactive carbon cycle in the
CMIP5 simulations. NASA has been trying to launch a satellite to measure global carbon, an
effort which remains troubled and plagued by continuing delays.

JC comments: If Salby’s analysis holds up, this could
revolutionize AGW science. Salby and I were both at the University of
Colorado-Boulder in the 1990′s, but I don’t know him well personally. He
is the author of a popular introductory graduate text Fundamentals
of Atmospheric Physics. He is an excellent lecturer and teacher,
which comes across in his podcast. He has the reputation of a thorough
and careful researcher.

While all this is frustratingly preliminary without publication,
slides, etc., it is sufficiently important that we should start talking about
these issues. I’ll close with this text from Bolt’s article:

He said he had an “involuntary gag reflex” whenever someone said the
“science was settled”.

“Anyone who thinks the science of this complex thing is settled is in
Fantasia.”

I am not a Scientist and as such have no credibility but my god it doesn't take a genius to understand the basics of atmospheric warming and be able to read a simple graph that shows temperature goes up first followed by CO2. You need to ask if CO2 is the driver of temperature why does the Earth release more when it warms and if CO2 makes the temperature go up what makes CO2 go down? If CO2 warms at low temperature, neutralizes at mean temperature and cools at high temperature it would put the graphs in perspective. Just as H2O is ineffective at low temperature, creates and increases temperature at mean and rises and cools to maintain temperature. Maybe if the atmospheric composition was examined as a whole we would conclude the Sun sets the maximum and the molecules and the surface of the earth reduce it and conserve it. Whether I'm right or wrong but I do know there's a lot more to how our atmosphere works than one molecule called CO2.

About Me

Apr 2017 - 4.1 Mil Pg Views, March 2013 - Posted my paper introducing CLOUD COSMOLOGY & NEUTRAL NEUTRINO rigorously described as the SPACE TIME PENDULUM, September 2010 I am pleased to report that my essay titled A NEW METRIC WITH APPLICATIONS TO PHYSICS AND SOLVING CERTAIN HIGHER ORDERED DIFFERENTIAL EQUATIONS' has been published in Physics Essays(AIP) and appeared in their June 2010 quarterly. 40 years ago I took an honors degree in applied mathematics from the University of Waterloo. My interest was Relativity and my last year there saw me complete a 900 level course under Hanno Rund on his work in relativity,as well as differential geometry(pure math) and of course analysis. I continued researching new ideas and knowledge since that time and I have prepared a book for publication titled Paradigms Shift&. I maintain my blog as a day book and research tool to retain data and record impressions and interpretations on material read.
